United States Patent AlPLlCATGR ATTAQHMENT FER PRESURE George 53. Diamond, Glen @ardner, Nl, assignor to Glen Gardner Corporation, Glen Gardner, Ni, a corporathan of New .lersey Filed Aug. 13, E53, Ser. No. 3lllfl39 9 Claims. (QR. 15-552) The present invention relates to a pressure dispenser, such as an aerosol can, particularly to a pressure dispenser of the type provided with an axially extending, elongated, tubular discharge nozzle at the base of which there is disposed, within a resilient body the outlet valve that may be opened by the tilting of the nozzle for the discharge of the can contents. More particularly, the present invention relates to an applicator attachment for the nozzle of such pressure dispenser.

Pressure dispensers of the character described, are frequently used to dispense material that requires processing after it is deposited on a surface. Such material may comprise, for example, a liquid adhesive that requires to be spread to a thin layer, over the surface to which it is applied, or it may comprise grout or calldng material that requires to be pressed into a groove or cavity that has to be filled. Heretoiore, in order to spread the liquid adhesive or to press in grout or calking material, a separate applicator or implement or device was required. Such implement could not be attached to the nozzle of the pressure dispenser can because the use of the implement required pressure against the surface being treated and when pressed against the surface, would tend to tilt the nozzle to open the valve of the dispenser and cause undesirable dispensing of its contents. The use of a separate, individual applicator for the purpose described, involves substantial inconvenience to the user and, frequently, waste of time that might be caused, especially by misplacernent of the applicator.

It is an object of the present invention to provide applicator attachment or accessory for the nozzle of a pressure dispenser can which will permit the dispensing of material from the can when desired and may be used as an applicator without risk of dispensing of material from the can when used as such.

It is also an object of the present invention to provide an applicator attachment accessory for a pressure dispenser can nozzle of the character described, which is easy and convenient to use and may be removed and transferred, as desired, from can to can.

It is another object of the present invention to provide an applicator or attachment or accessory for a pressure dispenser nozzle, of the character described, which is of relatively simple construction and economical to produce.

It is a further object of the present invention to provide applicator attachment or accessory for a pressure dipenser nozzle, of the character described, which is highly efiicient and reliable for its purposes.

The foregoing and other objects and advantages of the accessory attachment to pressure dispenser of the present invention will become more readily apparent to those skilled in the art from the embodiment thereof shown in the accompanying drawings and in the description following. It is to be understood, however, that such embodiment is shown by way of illustration only, and without any intent of limiting the invention to the specific details therein shown.

In the drawings:

FIG. 1 is an exploded view of the applicator attachment of the present invention with the nozzle end of a pressure dispenser can on which it may be used;

FIG. 2 is a longitudinal sectional and partly elevational view of the applicator attachment or accessory, in posiddd'fl dl Patented Aug. 3, 1965 tion upon the nozzle of a pressure dispenser can, in dispensing position;

FIG. 3 is a view similar to that of FIG. 2 with the attachment shown in position for use as an applicator;

FIG. 4 is a section takenon line 44 of FIG. 3; and FIG. 5 is a perspective view of the end section of the applicator attachment, with its discharge side uppermost. Referring now in greater detail to the embodiment of the invention shown in the accompanying drawings, the numeral 1% designates a pressure dispensing can of a conventional type, having an opening, 312, defined by an outwardly curved beaded edge, 14, and an inwardly directed cup-shaped closure, 16, set into the opening 12 and formed with a curved lip, 18, fitting over the beaded edge 14, of the can opening. The closure 16 is provided with a center opening over which is set a resilient cylindrical stud, 19, which houses an outlet valve (not shown) and above which is mounted an elongated tubular nozzle, 20, having a flared base forming a shoulder, 22, that rests on the resilient stud, l9, and slightly overlaps it to form the undercut shoulder 23. This conventional pressure can may be used to discharge its contents through the nozzle 2!? by tilting the latter in any direction, which results in the opening of the valve, as is well known in the art.

The applicator attachment of the present invention mayv consist of a tubular portion, 26, adapted to fit snugly over the inner end of the nozzle 2d and a flared base portion 28, adapted to fit over the shoulder 22 of the nozzle. The base portion 23 may be formed with an inner rib, 259, at the bottom of its flare, which is adopted to snap over and engage under the shoulder 23 of the nozzle base 22 to retain the applicator section 24 in place. The base portion 28 is also formed with a lateral extension on foot, 3? of a length to overlie the curved lip ll?) of the closure 16 and in position to contact it when the flared base portion 23 of the attachment section 24 is engaged on the shoulder 22. T he foot 3d may be provided with dependent prongs a length to overlie thec urved lip 18 of the closure 16 and may frictionally contact its inner surface.

The applicator also comprises a second section generally designated as 36, consisting of a tubular portion, 38, adapted to frictionally engage over the end portion of the nozzle 20 and having its end cut away along converging oppositely facing planes to provide a tapered end portion, 48, to the edges or which are secured a pair of converging plates, 42 and 44, which close oii the end of the tubular portion 33. Sue of the plates, as 42, is formed with a discharge opening, 46, that communicates with the outlet of the nozzle 26. The other of the plates, 44, may have its outer surface shaped to perform the processing of the dispensed material, as a flat surface shaped to act as spreader and to wipe off excess material, as illustrated. Where the discharged material is of a nature that requires spreading, as glue, the plate 42 may be formed with low squared ribs, d7, along its side edges, to spread the discharged glue in a layer of applicable thickness.

While the attachment of the invention may have its two sections 2.4 and 36 integrally formed, with the foot 39 extending from the sleeve. section 26 on the same side with the apertured plate d2, it is preferred to have the two sections of the attachment 24. and 36, separate from one another so as to enable the use or" its first section 24 with second section 36 of different forms or shapes. When so formed in two separate sections, and to the end that the foot 39 will always be in properly oriented relation relative to the discharge opening, 46, the inner end of the tube portion 33 of the second section may be provided with notches or recesses, 48, and the outer end of the tubular portion 25 of the first section 24, may be provided with projections, 54 fitting into the recess 43; the recesses and projections being so arranged as to orient the two sections of the attachment in proper relation to one another, to have foot 3% and opening 46 face in the same direction.

The operation of the attachment of the present invention will be clear from the foregoing. In preparation for use, the first section 24 is fitted over the inner end of the nozzle 29 and snapped over the edge of its base 28, with the end of'the foot 30 overlying the edge 13 of the closure 16 and in contact therewith and its teeth or prongs 32 extending into the interior of the closure. The second section 36 of the attachment is then slipped over the end of the nozzle 20, with the projections 50 and recesses 48 interfitted so that proper orientation of the discharge opening 46 and foot 30 is arranged. The friction fit of the tubular portion 26 of section 24 over the nozzle will maintain it securely in place on the nozzle.

In order to discharge the contents of the dispenser, the applicator end of the attachment is applied against the surface, 54, to be coated, with the plate 42 having the opening 46 facing such surface. Pressure of the applicator against the surface 54 will cause the nozzle 20 to tilt and open the discharge valve of the can without any interference from the foot 30, which will be tilted away from the edge of the closure as clearly seen in FIG. 2. The discharge material will pass into the tapered space between the two plates 42 and 4-4 and through the opening 46 on to the surface 54. The discharged material will be spread into a layer of applicable thickness, by the movement of plate 42 over the surface. The can is then rotated in the hand, 180, so that the surface of the other plate 44, and its pressure against the treated surface 54 will not cause any tilting of the nozzle 20 to discharge position; such movement being inhibited by the contact of the foot with the edge 18 of the closure 16. When the base 22 of the nozzle 20 is in such elevated position that the foot St! is disposed in spaced relation above the lip 1% of the closure 1d, as may happen under the pressure of a full can, which may press outwardly and elevate the stub 19 and nozzle 20, the movement of the nozzle to discharge position will be inhibited by the contact of the prongs 32 against the inner surface of the wall of the closure 16.

This completes the description of the applicator attachment of the present invention. It will be clear that such attachment may have applicator portions of varied shapes for varied purposes. It will also be apparent that the attachment of the present invention is simple, easy and safe to use and is highly efiicient for its purposes and affords great convenience to the user.

It will be further apparent that numerous variations and modifications may be made in the'applicator attachment of the present invention, by any one skilled in the art, in accordance with the principles of the invention hereinabove set forth and without the exercise of any inventive ingenuity.
